Получение соединений несмешиваемых материалов W-Cu и W-Ag с помощью высокотемпературной плотной азотной плазмы на установке ПФ-4
This is a continuation of research on shock alloying metals chemically interacting elements with concentrated flows of energy [1-6]. It has been shown that under the influence of high-temperature plasma stream of the plasma at focus type plants can be produced pseudoalloys tungsten-copper, copper-niobium. Welding was performed in a solid state immiscible wafer W and copper obtained low-resistance electrical contacts ~ 10-6 Ohm * m, suitable for electrical power equipment. High speed particle penetration of copper (Cu) and niobium (Nb), tungsten and copper in the substrate to a depth of more than 2 ÷ 20 microns provides good adhesion obtained pseudo W-Cu and Cu-Nb. It is known that tungsten pseudoalloys with copper and silver are widely used in various power switches electric current [7]. Service life of the current switches pseudoalloys 6 times the performance of current switches with copper plates. However, production of W-Cu pseudoalloys and W-Ag powder metallurgy method is rather time consuming and costly process [7].
Getting pseudo W-Cu and W-Ag on the pulse of high-energy plasma systems such as plasma focus (PF) is a simple process that does not require time-consuming training materials.
The aim of the work was to obtain the electrical contacts on the basis of pseudo W-Cu and W-Ag, as well as their compositions W-Cu, Ag for low-current electronics and microelectronics on the installation type PF.
